An electric-powered bulk material dispersing system and method of use. The electric power is provided by a battery system with one or more electric motors to replace traditional internal combustion engines. The electric motor or motors are used to provide pressure to one or more pumps that may be used in conjunction with various tubes, hoses or related conduit and spray nozzles in order to disperse a bulk material such as seed, mulch, compost, chipped wood, grain, hay, fertilizer, herbicide, pesticide, plastic pellets, salt, sand or the like that has been combined or suspended within a fluent material. In one form, the bulk material dispersing system may be used as a bulk hydroseeder.
